CALIFORNIA, U.S. - Facebook is doing all its can to retain its users and make them stay on for longer periods of time.

Facebook’s new addition, that was reportedly rolled out to select users now lets them order food through the social network - without having to leave the safe confines of social media.

The new addition showcases a hamburger-styled light blue "Order Food" icon in the Facebook app's menu area on mobile phones, while a more realistic looking hamburger appears on the sidebar on the Facebook website.

The addition lets users order their favourite takeout from the restaurant up the street without leaving their desk.

The system is reportedly powered with Delivery.com and Slice, which is an enhancement of an earlier feature that allowed users to order directly from a restaurant's Facebook page.

When a user taps through to the new food ordering icon on Facebook, a list of restaurants in their area that use the service show up.

Then, when a user taps on the restaurant's image - they are taken to its Facebook page, or they can just hit Start Order to get directly to the menu.

Users are then allowed to enter their address to ensure the place can deliver to their location or inform the restaurant that they would pick up their order.

In what seemed like a straightforward interface for ordering - Facebook is hoping that ordering food directly from within the social network could make it more convenient for users that don't want to figure out which restaurants in their local area have online ordering.

Users would also not have to navigate to an eatery's Facebook page anymore, either.
